I am trying to find the best solution to estimate equal distribution of points over a line. I know I can use relative SD or similar, but I was wondering if there are more "specific" methods that can ...

i'm looking for on how to calculate the following ICs: smoothing, on-line filter and prediction on state space models.
I'm not able to find any formula about them or any matlab command/class.
Thanks....

I want to determine the LRS lambda of a lognormal distribution under H0: the variances are equal.
What I have so far is the following:
$H0: \sigma^2 = \sigma_{o}^{2}$
$H1: \sigma^2 =! \sigma_{o}^{2}...

I am struggling a little to know if I am comparing independent or not independent data and I am not sure what kind of test I should use.
Here is the pitch : I would like to compare latencies between ...

Possibly a very basic question, but I would really appreciate clarification from those with a strong background in stats/epi.
I have a number of human patient medical records. They are retrospective ...

I'm trying to simulate the tail values from a multivariate distribution using copulas. I'm using Vine Copula package of R to derive the suitable copula for my data and I generate random samples out of ...

I am trying to evaluate the different ICA algorithms using MATLAB. To do that, one of the measure which I use is to estimate the non-gaussianity using NegEntropy. I am trying to find a function which ...

My Problem goes like this:
Suppose the cities of world, each city has a degree of economic collaboration with other cities. I need to detect communities such that the degrees among different cities ...

I am doing a simple moderation analysis with one independent variable (IV), one moderator (M) and one dependent variable (DV).
Results indicate that a regression model containing both main effects (...

I have precipitation data of around 40 years of 10 stations but some missing data in the middle. I want to check whether the precipitation has changed significantly over the decades in the region so ...

Let $X\sim Bin(n,p)$. The problem is to show that a UMVUE can exist for $g(p)$ only if $g(p)$ is a polynomial in $p$ of degree at most $n$.
For the case when $g(p) = \frac{1}{p}$ we can show that it ...

I want to get Bayes factors for ANOVAs that are analogous to the classical F-tests, and I just want to make sure I understand correctly how to write the syntax, especially regarding subject IDs.
For ...

I create an application with some social interaction between users. Users will have ratings that determines your recommendations - users are recommended to users with the same rating.Total rating of ...

As a part of a study, a survey to measure the impact of an environmental education project is being developed, and to do so, factor analysis and principal component analysis are being performed for ...

I’ve recently started learning about neural networks and currently am working on a NN to classify images of a cat vs non cat. I’ve built an option of customizing the number hidden layers and nodes per ...

Suppose we have independent (not necessarily identical) normally distributed random variables X, Y. If we're given that, upon sampling each variable, X is some multiple a of Y (i.e. x = ay), what is ...

I am not familiar with LASSO regression in R and generally with the field of statistics. I want to perform LASSO regression with continious variables. I tried everything that exists in google and in ...

I have a split splot full factorial design : 3 blocks, each block contains 4 plots for factor E and each plot is divided into 3 subplots for factor F. I use a mixed effect model with random effects on ...

Is there a place where one can get standard example data for various statistics tools to try on? For example, if one is learning about ARIMA models, where would one get data that can be modelled well ...

Consider a vector $v$ such that $v \sim \mathrm{Unif}(\mathbb{S}^{d-1})$, the uniform distribution on the unit sphere in $d$ dimensions.
Question: is there an upper bound on the probability that $v$ ...

I am working with collaborators who are conducting an education research study to see if there is a difference in learning outcomes between two learning experiences, one with a technology tool (let’s ...
